Trading Systems Reliability Engineer (C++)

Qube Research & Technologies

Qube Research & Technologies (QRT) is a global quantitative and systematic investment manager, operating in all liquid asset classes across the world. We are a technology- and data-driven group implementing a scientific approach to investing. Combining data, research, technology, and trading expertise has shaped our collaborative mindset, which enables us to solve the most complex challenges. QRT’s culture of innovation continuously drives our ambition to deliver high-quality returns for our investors. You will join the Core Trading Platform team, which is responsible for the design and operation of QRT’s global electronic trading infrastructure. This team builds and maintains the ultra-low latency systems that underpin real-time trading, managing performance-critical workflows across global markets. You will work closely with developers, traders, and operations to optimise system behaviour, reduce latency, and ensure platform reliability at scale. Build. Break. Investigate. Optimize. Repeat. We're looking for engineers who love understanding how systems really work. Tinkerers. Optimizers. Troubleshooters. Performance sleuths. People who are just as comfortable diving into Linux internals and packet captures as they are writing software to eliminate operational toil. This isn't a traditional support role. You'll operate at the intersection of software engineering, production operations and business workflows, helping keep a fast-moving trading platform running reliably while continuously making it better.   What you'll do: Own production * Take responsibility for the health, stability and performance of critical trading systems. * When things break, you're one of the people everyone wants in the room. * When things don't break, it's often because of something you built. Investigate the unexplained * Chase down complex incidents that span applications, infrastructure, networks and market connectivity. * Become a technical forensic investigator, uncovering root causes that aren't immediately obvious and turning every incident into a learning opportunity. Eliminate toil * If you have to do something twice, you'll probably automate it. * Build tools, workflows and self-service capabilities that make systems easier to operate and engineers more productive. Obsess over reliability * Design better monitoring, observability and alerting. * Measure what matters. * Reduce noise. * Increase signal. * Help us understand our systems before they fail rather than after they fail Understand the business * Our systems exist to support trading. * You'll learn how orders move through the platform, how market data flows, how trading desks operate and why reliability matters to investment performance. Optimize everything * Latency. * Efficiency. * Deployments. * Troubleshooting workflows. * Feedback loops. * Engineering productivity. * Nothing is ever "good enough." What we're looking for You might be a good fit if you: * Enjoy taking things apart to understand how they work * Automatically start troubleshooting when something looks wrong * Find repetitive work deeply irritating and automate it away * Get satisfaction from building reliable systems * Prefer solving root causes instead of treating symptoms * Love learning new technologies and diving into unfamiliar systems * Can communicate clearly during high-pressure production events We're more interested in how you think than the exact technologies you've used, but you'll likely have: * Strong software engineering skills in Python, C++, or another modern programming language * Solid Linux systems knowledge * Understanding of networking fundamentals including TCP/IP and multicast * Experience troubleshooting distributed systems * Familiarity with observability, monitoring and automation tooling * A passion for engineering robust, scalable and operable systems Previous experience in finance or trading is helpful but not required.   Why this role is different Most companies separate developers, operations engineers and production support teams. We don't. You'll join a multi-skilled engineering group that combines software development, production engineering, operational ownership and business understanding. The result is a role with a broad scope, a steep learning curve and the opportunity to have a direct impact on the reliability and performance of a global trading platform.   QRT is an equal opportunity employer. We welcome diversity as essential to our success. QRT empowers employees to work openly and respectfully to achieve collective success. In addition to professional achievement, we are offering initiatives and programs to enable employees achieve a healthy work-life balance.

Flow Traders

Flow Traders is looking for Senior C++ Software Engineers to join our growing team in Hong Kong. Software Engineers at Flow Traders provide us with our competitive edge, equipping Researchers and Traders with the information and capabilities that they need to make sound business decisions. C++ plays a critical role in our event-driven trading systems, which are designed to reliably handle vast amounts of data at ultra-low latencies. As a C++ Engineer, you will build systems used to analyze and trade tens of thousands of products across hundreds of global trading venues every day. Working closely with Technologists, Quantitative Researchers, and Traders, you’ll guide the development of our in-house trading technology and optimize it to achieve market-leading performance and reliability. Our proprietary trading platform includes everything from venue connectivity (feed handlers and ordering gateways) to trading engines to shared platforms that enable us to work quickly and efficiently - we are proud of our open and collaborative culture, so you’ll have plenty of opportunity to find what fits you best. Teamwork is one of our most important firm values, and end users are never more than a short walk away, guaranteeing short feedback loops and immediate insight into the value that your code provides. To foster collaboration and innovation, we maintain shared libraries, encourage code re-use, and continuously evolve our views on application architecture.     WHAT YOU WILL DO: Main technical activities include: For all C++ openings: * Lead the development and global rollout of our Core platform used in multiple business/focus groups (Market data, Quantitative research, Pricing, Strategies) * Be involved in the development process, which will be a fast-paced iterative process where you deploy your deliverables and validate them yourself and/or together with traders or quants * Develop tools/frameworks to deliver capabilities for tuning/develop data-driven systematic pricing and trading strategies * Work together with focus group engineers, Quants and Technical traders to refine requirements, collect feedback, and iterate on design and implementation of platform requirements   Exchange Connectivity: * Write software that communicates with exchanges through their APIs, receiving market data and sending orders over the network in different protocols, such as FIX, Websocket or HTTP requests * Ensure quality of software based on a set of testing suites, which you are expected to use, maintain and extend * Optimize exchange communication through kernel bypass, optimizing TLS or the connection handling to an exchange * Research exchange behavior in detail to align our behavior to that of an exchange * Implement these solutions using the provided exchange SDKs in different languages such as C++, Rust, Python, Typescript   Trading Strategies: * Implement trading algorithms based on requirements provided by traders and quants * Acquire and develop the necessary trading knowledge to successfully translate the requirements into actual software implementation * Continuously improve the stability, reliability, and performance of the trading engine * Enhance monitoring and observability in collaboration with the Trading Operations team * Investigate and resolve production issues such as crashes, unexpected business logic behavior, and performance bottlenecks * Prepare for releases and deployments of new trading engine versions   WHAT YOU NEED TO SUCCEED   * BSc, MSc, or PhD in Computer Science, Mathematics or equivalent * 5+ years post-graduation professional C++ software development experience (proprietary trading industry preferred) *  Ability to write clean, reliable, and highly scalable code * Good knowledge of algorithms and data structures * Experience in parallel, asynchronous, and multithreaded programming *  Interest in achieving maximum performance from available hardware and software *  Ability to communicate with technical and non-technical business colleagues   Flow Traders does not accept unsolicited resumes from any professional staffing or search firms.
